\[ \boxed {y^{2} x +x^{2} y y^{\prime }=6} \]

Solution by Maple

Time used: 0.0 (sec). Leaf size: 30

dsolve(x*y(x)^2-6+x^2*y(x)*diff(y(x),x)=0,y(x), singsol=all)
 

\begin{align*} y = \frac {\sqrt {12 x +c_{1}}}{x} y = -\frac {\sqrt {12 x +c_{1}}}{x} \end{align*}

Solution by Mathematica

Time used: 0.19 (sec). Leaf size: 38

DSolve[x*y[x]^2-6+x^2*y[x]*y'[x]==0,y[x],x,IncludeSingularSolutions -> True]
 

\begin{align*} y(x)\to -\frac {\sqrt {12 x+c_1}}{x} y(x)\to \frac {\sqrt {12 x+c_1}}{x} \end{align*}
